"I decided to stop because I didn't think MMA was motivating me enough to keep dedicating myself 100 percent to an athlete's life," Gracie said in an interview with MMA Fighting.
I enjoyed it, it was a huge pleasure to do these 10 MMA fights, but I have no other ambitions. I just turned 36. I never wanted to compete longer than 38, and there's not much else left to conquer in MMA, something that would change my career."I just ended my career at a high level. I would have more to lose than to gain if I kept fighting MMA. If I had the same passion in MMA like I had in jiu-jitsu I would continue, but the only motivation that would keep me in MMA was money, and I'm against doing something focusing only on money. I don't think I'd even give my 100 percent in this case, so I decided to retire and focus on other things in my life."
Gracie is one of the most accomplished of all jiu-jitsu competitors with 10 IBJJF world titles. He is also a two-time ADCC champion and ADCC superfight champion.
He announced his retirement from jiu-jitsu after defeating Marcus 'Buchecha' Almeida in a superfight in July at Gracie Pro, an event in Rio de Janeiro.
Gracie says his focus from here on out will be on teaching at his gym in London and developing his team.
